Food prototype containing resistant starch type 4 on postprandial glycemic response in healthy adults
Bibliographic record
Abstract
Resistant starch (RS) is a variant of starch that is indigestible by human enzymes and has been acknowledged for multiple physiological benefits including attenuation of postprandial glycemia when incorporated into foods. Distarch phosphate is a RS type 4 (RS4) containing phosphodiester cross-links within and between starch molecules. Considering the importance of RS to human health, the present study aimed to investigate the dose response effect of a novel RS4 (potato-derived distarch phosphate - (VERSAFIBE 1490™) on acute postprandial glycemic responses compared with energy/available carbohydrate and sugar-matched control. The study was designed as a controlled, single-center randomized, single-blinded, cross-over trial, in which 31 healthy adults consumed a baked breakfast cereal bar containing 0, 10 or 20 g RS4 followed by serial blood samples over two hours to determine glucose and insulin concentrations and calculate the incremental area under the curve (iAUC). Results suggest that the addition of RS4 did not reduce iAUC glucose or insulin responses significantly (P > 0.05) at the doses provided. No significant changes in the glucose or insulin maximum concentration (Cmax) and time to reach maximal glucose and insulin concentrations (Tmax) were observed (P > 0.05). Overall, this particular RS4 did not affect measures of glycemia in healthy individuals at doses provided in ready-to-eat baked-good.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedLabeled directly by 2 models reading the full record.
